Effect of catagenetic transformations on filtration-capacitive and elastic properties of carbonate rocks
Secondary transformations of carbonate rocks of the Late Cambrian age of the Nepa-Botuoba anteclise significantly change the filtration-capacitive properties that can lead to both improvement and deterioration of the reservoir characteristics of these rocks. An extensive petrophysical collection of samples was analyzed to study the development of secondary processes, including salinization of pore space with halite. Examples of the effect of the complex multicomponent rock composition and secondary processes on the elastic properties of rocks. These were determined from the data of an extended set of logging and wave acoustic logging methods are shown
Estimation of fractures of deep sediments of southern part of the Ural foredeep based on results of geomechanical modeling
The paper discusses the conditions of formation and development of reservoir properties (porosity and permeability) at great depths of the Earth’s crust. Using geomechanical modeling technology, secondary permeability of deep Paleozoic deposits of the southern part of the Ural foredeep was estimated. The carried out research allowed to reveal the areas of increased fracture values. These zones are the most favorable for hydrocarbon accumulations search in the southern part of the Ural foredeep
Integration solution for information model of offshore oil and gas facilities under construction and assembly
The paper examines the implementation of information modeling and integration systems for project management. Demonstration schemes of integration models for the construction of offshore oil and gas facilities have been developed. In addition to the above, applied problems are considered at this stage and ways of solving them are described in detail. This allows to effectively interact with project participants, track collisions and monitor the progress of work
Main aspects of determining the drag reducing agents quantity in the contact area by batching technology
As is known, drag reducing agents (DRA) reduce not only the hydraulic resi-stance coefficient but also the turbulent diffusion magnitude of a moving fluid. When the mixture area moves through the pipeline, the concentration of the DRA gradually decreases, which leads to a decrease in its efficiency. The article deals with the main aspects that affect the determination of the amount of DRA added to the contact area under batching technology
Method of determining dimensions of corrosion defects of elements of offshore oil and gas facilities based on their temperature state
Offshore oil and gas field facilities are exposed to various impacts, corrosion being the most intensive. The results of the experiments are presented and a technique is proposed for estimating the size of corrosion defects on the basis of the difference between defect-free and corrosion-affected zones. The technique will allow to determine with a high efficiency the dimensions of corrosion lesions and to evaluate their impact on the safety of operation of offshore oil and gas facilities
Uninterrupted operation of gas supply systems as main task of gasification
The main ways of solving the problem of trouble-free and uninterrupted gas supply to consumers through gas distribution networks by ringing the network to create closing areas are considered. The measures and actions necessary to accomplish the task are described
Analysis of current methods to combat losses of oil and petroleum products
This article estimates the losses of oil and petroleum products during transportation, storage and distribution. The shortcomings of the current methods have been analyzed and identified. The necessity of carrying out new studies on separate accounting and distribution of losses is substantiated
Forced oscillations of axes of wheels of the dissolution during transportation of pipe strings on rough roads
In this article statistical information of such parameters is considered as: moving, speed and acceleration of axis is wheels which depend on the radius of wheel and are of interest for a dynamic calculation on durability and crumpling of the transported lashes on the dismissal of trubovoza-pletevoza of different extent. In investigation of it at the experimental study of travelling burries it is necessary to get information, characterizing moving, speed and acceleration of axis of wheel, rather than just type of roads and its statistical parameters
Study of acoustic emisiion signals, generated by corrodible carbon steel
The results of research conducted to determine the possibility of application of acoustic-emissive method for the exposure of corrosion of carbon steel are pre-sented. The developed methodology allowed steady separation of acoustic sig-nals, characteristic for dissolution of metal, from those characteristic for the selection of hydrogen. It is determined that basic identification parameter of the signals characteristic for dissolution of metal is their frequency of the basic maximum of energy equal to 50 khz. The results can be used to improve the systems of acoustic-emissive corrosive monitoring
Specific features of development of draft national standards for import substitution of oil and gas facilities inRussia
The paper considers the specifics of developing the Russian national standards that provide solution to the problem of import substitution for oil and gas complex facilities. The activity of industrial technical committees on standardization is analyzed, the necessity of development of fundamentally new draft standards aimed at increasing the competitiveness of domestic oil and gas equipment is substantiated
A new method for rolling threads is proposed. This extends the technological possibilities of the thread-rolling process with tangential heads by machining threads that are not limited in length to the rollers, as is the case with tangential heads. This allows to control the size and direction of the working axial feed of the rolling rollers, by varying the diameter and therefore the angle of inclination of the threads of the rollers, which in its turn allows to take into account the specific technological conditions of the processing. This is achieved by the fact that the combination and sequence of the types of working feeds and a new mutual initial setting of the rolling rollers and parts are regulated, which, when co-executed, rolls the threads of unlimited length when using tangential thread rolling heads
Logic of automatic systems protection against loss of stability of industrial electrotechnical systems
The article is devoted to solving the actual problem of protection of electrical systems of industrial enterprises from the loss of stability in external disturbances. The algorithms of work of emergency protection systems based on digital high-speed microprocessor systems are presented and substantiated
Problems of competitiveness of small-sized oil and gas pipeline devices in Russia
The paper analyzes three main interrelated components of the competitiveness of domestic industrial products using the example of the most mass products of gas-oil engineering. It is shown that the quality of modern small-sized oil and gas pipeline devices is economically effective to be focused on the wear resistance of the sealing elements of oil and gas pipeline devices structures. The analysis of the second component of the competitiveness — innovations in the domestic armature construction — showed that copying of the samples of foreign oil and gas pipeline devices can be a deadlock for import substitution. Consideration of the third component — the Russian inventions — indicates the urgent need for moral and material incentives to generate new ideas and bring them to implementation. All participants should be interested in this: the consumer, the inventor, the manufacturer and various kinds of assistance funds (venture firms, the so-called incubators, etc.)
Comparative experience of using various fluids in the processes of well con-struction and repairs, formation drilling and killing a well, as well as intensification of oil production and enhanced oil recovery, shows high efficiency of emulsion compositions. At final stage of oil fields development these compounds find a wide application in various enhanced oil recovery technologies.
Synthesis of surfactants which are emulsifiers component of direct and invert emulsions was carried out by sulfonation of technical fish oil (waste from the fish processing industry) with specific fraction composition of fatty acids. The possi-bility of using the obtained emulsifier as an emulsion composition component for enhanced oil recovery is shown and application efficiency is estimated
Peculiarities of phase equilibrium of nitrogen-light hydrocarbons mixture
Thermodynamic research on phase equilibrium of natural gas components mixtures plays an important role in the technological processes design for LNG plant. As liquid-vapor equilibrium issues of natural gas systems have been studied well, at present research is concentrated on multiphase systems, containing mixtures of hydrocarbons with inorganic substances, such as water, carbon dioxide, hydrogen sulfide, nitrogen, hydrogen. Issues of phase equilibrium of binary, ternary and 4-component mixtures containing methane, ethane, propane and nit-rogen are considered. It is outlined that nitrogen-hydrocarbon mixtures could display properties of both mutually soluble substances and partially soluble ones, depending on thermodynamic conditions and components content ratio. Areas of existence of three-phase systems „liquid-liquid-vapor” were calculated. The results obtained are of great importance in LNG processes design and moderniza-tion, as well as in the development of processes of nitrogen extraction from natural gas
Evaluation of lewis acidity of solid oxocomplex catalysts for isomerization of light hydrocarbons
A new catalyst for isomerization process of light hydrocarbons based on novel synthesized inorganic superacids has been developed. With this purpose a number of mixed heteropolyanions with a modified Keggin structure containing different transition metals (including platinum group metals) have been synthesized. The technology of preparation of superacid catalysts with a coating of mo-dified heteropolycomplexes on different carriers has been developed. Lewi acid characteristics of the developed superacid catalysts on different car- riers have been investigated
Nanostructured photocatalysts based on cadmium and zinc sulfide nanoparticles deposited inside/outside natural halloysite nanotubes
Novel nanophotocatalysts based on CdS or Cd(1-x)ZnxS nanoparticles less than 10 nm in size and mass concentration in catalyst of about 3–3,5 % deposited on outer and inner surface of halloysite nanotubes were synthesized and investigated. The obtained catalysts are efficient in reaction of hydrogen evolution from electrolyte solution under visible light irradiation. It was shown that the most active catalyst is a system with Cd0,3Zn0,7S nanopartilces deposited on halloysite, the hydrogen reaction rate reached 756 µmol/h·gkat
